REUEL H. WELGH, OF ST. LOUIS, MISSOURI.

PAPER-RULING MACHINE.

SPECIFICATION forming part of Letters Patent No. 564,67 2, dated July 28, 1896. Application filed February 25, 1896. Serial No. 539,589. (No model.)

To all whom it may concern.-

Be it known that I, REUEL H. WELCH, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented a certain new and useful Paper-Ruling Machine, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a new and useful improvement in rotary ruling-machines for paper.

The object of my invention is to produce a cylinder machine by means of which both sides of a sheet of paper may be ruled'with but one handling and which will accomplish this result with the use of, preferably, but one printing-roller. In machines of this type as previously constructed only one side of a sheet of paper could be ruled by feeding it once into the machine; but I have so constructed my machine that the paper, after passing over the printing-roller and being ruled on one side in the usual manner, is automatically returned in position to be ruled on the remaining side by the opposite side of the said roller, while at the-same time a new sheet may be printed on the first side. Thus not only is one handling of the paper saved, but the ruling is done with a rapidity which would require two machines of the old type.

In the accompanying drawings, which illustrate one form of my invention, Figure 1 is a top plan view of my machine. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged section on the line 3 3 of Fig. 1, the intermediate part and part of the tail of the machine being broken away.- Fig. 4 is an enlarged isometric projection of one end of the printing, inking, presser, and tape rollers and one of the supports in which they are carried. Fig. 5 is an enlarged isometric projection of one of the devices for tightening the tapes. Fig. 6 is an enlarged isometric projection of one of the ink-pans, part of the same being broken away. Fig. 7 is an enlarged isometric projection of one of the clamps for securing the inking-cloth to the ink-pans. Fig. 8 is an enlarged isometric projection of the device for regulating the pressure of the inking-rollers. Fig. 9 is a rear elevation of the support shown in Fig. 4. Fig. 10 is an enlarged isometric projection of one of the devices for controlling the pressure of the upper presserroller.

Like marks of reference refer to similar parts in all the views of the drawings.

is the frame of the machine and 16 the legs or supports upon which it rests. At opposite sides of one end of the frame are secured two similar supports 17. Said supports are each provided with a vertical slot 18 for receiving the guides 19, carrying the grooved presser-rollers 20, and the guide 21 carrying the printing-roller 22, with its series of disks, and the horizontal slots 23 for receiving the guides 24, carrying the inking-rollers 25 and 25. They are also provided with holes,which may receive the ends of the tape-rollers 26, 26 26 and 26, but preferably receive the pins 27 of the disks 28, Fig. 5, into the slots 29 of which the ends of said rollers are placed, thus giving means for tightening the tapes and thumb-screws 30 for securing said disks in proper position.

31'are the plates, (best shown in Fig. 8,) which are secured across the slots 23, Fig. 3, and through which pass the thumb-screws 32 for regulating the pressure of the inking.

rollers 25 and 25 Said plates are provided with springs 33 for holding said screws 32 in the position in which they are set.

34 are the ink-pans, Figs. 3 and 6, one of which is secured below the ink-roller on the side of the supports 17 nearest the feed end of the machine by means of the holder 35, Fig. 4, and the other of which is secured beside the other ink-roller by means of the supports 36, Figs. 2 and 3.

37 are the inking-cloths, Fig. 3, by means of which the ink is conveyed from the inkpans 34 to the ink-rollers 25 and 25 and which are secured to said pans by means of the clamps 38. (Best shown in Fig. 7.)

The disks carried by the printing-rollers 22, having'continuous printing edges, are ar-. ranged to come opposite the grooves in the presser-rollers 28, Fig. 4, so that the printingdisks will not ink the presser-rollers when no paper is passing through the machine.

The shaft of the lower groovedpresser-roller 2O terminates in the belt-wheel 39, Figs. 1 and 2, on the side of the machine, to which thedriving-belt 40 is led, and the opposite end of said shaft has secured to it the pinionwheel 41, Fig. '9, which engages with the spur-wheel 42 on the shaft of the printingroller 22. Said spur-wheel 42 also engages with the pinion-wheels 43 on the ends of the shafts of the inking-rollers 25 and 25 and the pinion-wheel 44 on the shaft of the upper grooved presser-roller 20. Said gear and pinion wheels are of such size that the periphcries of the printing, inking, and grooved presser-rollers will move at the same rate of speed. The shaft of the printing-roller 22 terminates at both ends in the beveled disks 45, Figs. 1 and 10, and the shaft of the upper presser-roller 2O terminates at both ends in the beveled disks 46, said disks serving to control the pressure of said presser-roller upon the printing-roller, said printing-roller 22 being held in position bythe pins 47, Fig. 4, on the supports 17 below the guides 21, carrying the shaft of said printing-roller, said pins being inserted after the guides 19 are in position. The pressure of the lower presserroller is regulated by means of a set-screw 48.

49, Figs. 2 and 3, are supports placed near the rear end of the machine, carrying the taperollers and 51, Fig. 3, and the shaft 52 on which are the wheels 53, which prevent the paper from turning over in falling from the upper to the lower tapes. The tape-roller 5O terminates on the front side of the machine in a belt-wheel 54, which receives the drivingbelt 40 and the belt 55, driving the wheel 39. Said roller also has secured upon it the gearwheel 56, Fig. 1, which engages with the gear-wheel-57, Fig 2, upon the roller 51, and thus drives said roller.

58, Fig. 1, is a tape-roller at the extreme end of the machine, carried in the supports 59.

are tapes, Fig. 3, leading from any suitable feeding device and passing around the roller 26.

61 are tapes or cords passing around the rollers 26 and 50.

62 are tapes passing around the rollers 58 and 51. Said tapes are preferably twisted, as shown in Fig. 1, so as to carry the sheet of paper some distance toward the front side of the machine and thus prevent the end of said sheet from striking the guide 63 and being turned around.

64 are tapes passing around rollers 51 and 26, and are twisted in the opposite direction to tapes 62, so as to bring the paper against guides 63, and thus feed it below the printing-roller in the right position.

65 are tapes passing around the roller 26 for carrying away the paper after it has been printed on both sides, and is preferably driven by the above-mentioned feeding device.

66, Fig. 3,-are sheets being fed through the machine.

The operation of my invention is as follows:

The sheets of paper 66 to be ruled are fed into the machine by the tapes 60, leading from any suitable feedin g device, pass between the upper presser-roller 20 and the printing-roller 22, and are then ruled upon the under side. The ink for this printing is supplied to the printing-roller by the inking-roller 25. They are then carried by the tapes 61 and under the wheels 53, until they drop upon the tapes 62. The center of said wheels 53 are situated slightly in front of the center of the roller 50, and thus the sheet of paper is held firmly down upon the tapes 61 after the center of said sheet has passed the center of the roller, and thus said sheet is prevented from turning over in falling from the tapes 61 to the tapes 62. The sheet is then conveyed toward the front of the machine by the tapes 62 and 64:, and passes between the printing-roller 22 and the lower presser-roller 20, and is thus printed upon the upper side. The ink for this printing is supplied to the printing roller by the inking-roller 25. The paper is then conveyed from the machine by the tapes 65, which are preferably attached to and driven by the above-mentioned feeding device.

I am aware that many changes may be made in the construction of my machine without departing from the spirit of my invention. Therefore I do not wish to be understood as limiting myself to the construction shown except when so specified in the claims.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a paper-ruling machine, the combination of a set of parallel ruling-disks having substantially continuous lining edges and rotating about a common axis, a pair of grooved presser-rollers cooperating with said rulingdisks to rule a sheet of paper on both sides, said presser-rollers being situated substantially opposite each other, a pair of inkingrollers for continuously supplying ink to the edges of said disks, a'conveyer presenting'one side of a sheet of paper to said disks to be ruled by the joint action of said disks and one of said presser-rollers, and a conveyer returning the sheet of paper so ruled to said disks and presenting the other side of said sheet thereto to be ruled by the joint action of said disks and the other of said presser-rollers, substantially as and for the purpose set forth.

2. In a ruling-machine, a printing-roller, presser and inking rollers for the same, a conveyer carrying the paper from the printingroller, a second conveyer below the first, returning the paper to the printing-roller, and a suitable pressure-applying device above the upperconveyer preventing the inverting of the paper in falling from the upper to the lower conveyer.

In testimony whereof I have hereunto set my hand and affixed my seal, this 23d day of February, 1895, in the presence of the two subscribing witnesses.
